java實現(xiàn)類似百文庫功能linux

1、實現(xiàn)類似百度文庫在線觀看功能目錄實現(xiàn)原理過程2資料和工具準備2工具準備和安裝2項目目錄及源碼5程序運行需要openoffice服務支持12實現(xiàn)原理過程網(wǎng)上大致看了下實現(xiàn)的方式,大體上有四種轉(zhuǎn)換的方式：1. Txt/Word/Excel/PPT=>PDF(OpenOffice+JodConverter)=>SWF(pdf2swf)=>FlexPaper瀏覽2. Txt/Word/Excel/PPT=>PDF(MSOffice+JACOB)=>SWF(pdf2swf)=>FlexPaper瀏覽3. Txt/Word/Excel/PPT=>SWF (Flas

2、hPaper)=> FlexPaper瀏覽4. Txt/Word/Excel/PPT=>SWF(print2flash)=> FlexPaper瀏覽資料和工具準備工具OpenOfficeJodConverterSwftools(pdf2swf)FlexPaper資料方面，大致搜索了百度文庫和開源中國上的一些資料，其實都大同小異。工具準備和安裝1. 安裝openoffice3，這個安裝過程很糾結(jié)，遇到過各種問題，因為先后在幾臺服務器上安裝過，最順利的安裝方法如下cd RPEMrpm -ivh *.rpm -nodeps force安裝后的默認目錄是在：/opt/目錄下面啟動服務

3、：/opt/3/program/soffice -headless -accept="socket,host=,port=8100;urp;" -nofirststartwizard &2.來安裝openoffice sdkcd OOO330_m20_native_packed-1_en-US.9567/RPMS/rpm -vih *.rpm3.JODConverter其實不用安裝 解壓了就行安裝jodconverter.2.2.2 ，安裝了這個之后就已經(jīng)可以實現(xiàn)DOC轉(zhuǎn)PDF了。解壓,復制到一個目錄里面去，就能直接用了

4、，調(diào)用它里面的/lib/jodconverter-cli-2.2.2.jar這個玩意兒就行，可以直接運行命令測試：順利的話就直接可以轉(zhuǎn)成功了exec("java -jar /home/download/jodconverter-2.2.2/lib/jodconverter-cli-2.2.2.jar /home/download/aaa.doc /home/download/1.pdf")4.Linux下安裝pdf2swf Tool中文支持安裝：1）  mkdir p /usr/share/xpdfcd /usr/share/xpdf/2） &

11、implified -s flashversion=9項目目錄及源碼工程目錄大致如下：另外，在lib下需要加入JodConverter壓縮包中l(wèi)ib目錄下的jar包，全部復制進去即可。ConvertServlet的servlet處理類代碼如下：package org.edc.test.servlet;import java.io.File;import java.io.IOException;import javax.servlet.ServletException;import javax.servlet.http.HttpServlet;import javax.servlet.http.
